GAS-BURN Specification of Letters Patent.

Application filled April 27, 1920. Serial No. 376,997.

T 0 all whom it may concern:

Be it known that I, J OHN FESTA, a citizen of the United States, andresidin at Brooklyn, Kings county, and New ork State, have inventedcertain new and useful Improvements in Gas-Burners, of which thefollowing is a specification.

This invention relates to gas burners and more especially to burnersused in heaters and its object is to provide a mixing chamber with ficesand extending upward from the chamber so that danger of back fire iseliminated and the flame is divided to permit of the the consumption ofmore oxygen while the mixed vapor is evenly distributed to each nipple,as willbe more fully described and the details enumerated in thefollowing specification and set forth inthe appended claims, andthedevice illustrated in the accompanying drawings, wherein:

Figure l is an elevation of the improved burner Fig. 2 is a verticallongitudinal sectional view of the same, v Fig. 3 is a plan view of theburner,

Fig. 4 is a cross sectional view onthe line 4-4. of'Fig. 2.

A serious objection to the burners com-. monly used in gas heaters isthe danger of back fire in consequence of the proximity of the nipple tothe gas inlet nozzle and the lack of air supply to all the gas jetsoften results in inefiectual combustion and-waste of gas. i i

To overcome these failures in burners as heretofore constructed, themixing chamber of the device shown in the drawlngs is divided into twocompartments 5 and 6, the latter receiving its supply of airand gasthrough the pipe 7, and from the inlet 8 and nozzle .9, of the supplypipe 10, to which may be secured suitable piping from the desiredsource. The nipple 9, is threaded and playing in the same, is the shield11, that may be advanced toward the open end of the inlet 8,sufiiciently to regulate the supply of air and be secured to anyadjust-' ment by the screw 12. r

The air and gas on leaving the pipe 7, are thoroughly mixed incompartments 5 and 6, by striking the partition 13, being deflectedlaterally and passing through the openngs, 14:, where on enteringcompartments 5, it 1s difiused o right and. left as its force is outletnipples divided at their orispent against the upper wall 15, and betweentwo of the nipples 16, at each side.

This arrangement of the mixing chambers insures a perfect distributionof the mixed vapor-to the nipples and where an identical volume of gasis furnished to each outlet. This can only be attained by supplying thevapor at a central point and not from one end and where the jets willdecrease in size toward the other end of the burner and where the supplyfor the last nipple is so weak that it will not remain lighted but allowthe escape of the gas to the room in which the burner is located.

The nipples 16'are made of short sections of pipe, threaded iand screwedinto holes that are tapped in the wall 15. Across the upper end isfitted a partition 17, of thin sheet metal and this end is compressedand flattened so that there is an orifice for the escape of vapor oneach side of the partition, thus providing for two parallel flames withspace between them for the admission of air on both sides and .it isevident-that by closing the orifices will provide a flame of greaterexpansion and more adaptable for heaters where reflection surfaces areused.

It will be seen that with a burner constructed as above described andillustrated,

it will be practically impossible for a flame to descend through thenipples, the two compartments 5 and 6, and the pipe 7, to the nozzle 9and fire the gas and supply at that point. It is also evident that thegas and air are evenly and thoroughly mixed in passing from the inletpipe to the nozzles by the arrangement of the compartments 5 and 6,. andthat the size of the jets is readily regulated by degree to which thenipples are compressed at their outlets.

Obviously the parts may be otherwise arranged and modified withoutdeparting from the essential features above described or from the scopeof the appended claim.

What I claim as new is In a gas burner, the combination of a horizontalcylindrical pipe having openings along its upper side and closed at itsends, a mixing chamber integral with the said pipeand having at itsseparate ends a communicating open1ng,a vapor supply pipe beneath themixing chamber andparallel with the same and the horizontal cylindricalpipe, nipples for the openings in the latter plpe and having slotted.orifices in line with and parallel with said horizontal cylindrical nameto this specification in the presence of ipe, and a dividing plate 'ineach slot two subscribing witnesses, this 20th day of adapted to dividethe flame so that the nip- April, 1920. ples Will supply two separateand distinct JOHN FESTA 5 and continuous flames along the pipes andWitnesses:
